Here Adoroma shows functions of the FlashPoint 8" HDMI LCD Monitor with Wireless Remote Shutter. Could be handy for still photographers, and for video the LCD can be used with the direct HDMI connection. The wireless video feature works through SD cables, and because it will disable the on-camera LCD (for DSLRs), I don't think it's a good solution for DSLR Video shooters.
It also doesn't have all the fancy focus peaking or exposure features of a real dedicated HD Video monitor. Still, if you have some other creative thoughts on to use this product Adorama normally lists the 8" HDMI LCD for $399 (seen here) and on Amazon it's being liquidated for $144 following the link (Click Here).
